Offer Description

The thesis will be carried out as part of a project funded (FRISBI project) by the PEPR batteries program. The work will involve collaboration between the Phenix laboratory and the LRCS.

Solid-state batteries could bring significant advances such as enhanced safety and higher energy yields. While most efforts are currently focused on lithium, a technology based on fluoride ions could exceed current expectations thanks to a charge carrier that is mobile and abundant (30 times more than lithium), intrinsically safe, and capable of giving rise to devices with high energy density (5 times more than lithium batteries). However, the youthfulness of such a system (proof of concept published in 2011) requires a great deal of further research, in particular into the integration of conductive compounds into an electrochemical device. Additionally, the redox mechanisms operating in these devices need to be better understood, notably using operando characterization techniques. Initially, this PhD thesis will explore the chemistry of tin-based fluorinated materials. The project will also study the integration of these materials into a complete device, targeting the study of redox mechanisms using advanced characterization techniques. A strong synergy between the project partners is expected to bring this thesis to fruition.
